Can I create a design concept that will improve safety for a SEATBELT?

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Consider a spherical container of inner radius , outer radius r2, and thermal conductivity k. express the boundary condition on the inner surface of the container for steady one-dimensional conduction for the following cases: (a) specified temperature of 50°c, (b) specified heat flux of 30 w/m2 toward the center, (c) convection to a medium at t with a heat transfer coefficient of h

Apiston-cylinder containing steam at 700 kpa and 250°c undergoes a constant pressure process until the quality is 70%. determine per kilogram (a) the work done, (b) the heat transferred, (c) then change of internal energy, and (d) the change of enthalpy
